3.3V PCI BUS QUAD UART
REV. 1.0.0
á
13
Registers INT3, INT2 and INT1 [32:8]
Twenty four bit encoded interrupt indicator. Each channel’s interrupt is encoded into 3 bits for receive, transmit,
and status. Bit [10:8] represent channel 0 and go up to channel 3 with bits [19:17]. The 3 bit encoding and their
priority order are shown below in
Table 5
. The Timer and MPIO interrupts are for the device and therefore they
exist within channel 0 space and not in other channel interrupt.
